The Current State of Refractive Surgery

The leading topic of this particular paper is dedicated to available surgical options for refractive eye disorders treatment including surgery of cornea and intraocular surgery. Corneal Surgery includes laser refractive surgery LASIK (Laser-Assisted In Situ Keratomileusis), FemtoLASIK (Femtosecond - laser assisted LASIK), PRK (Photorefractive keratectorny). This article describes relevant principles of particular procedures, indications and possible contraindications. The chapter dedicated to corneal implants provides information about ICRS (Intrastromal Corneal Rings Segment) and Inlays (corneal implants for presbyopia correction). Corneal interventions also include incision methods for astigmatism correction AK (Astigmatic Keratotomy) and LRI (Limbal relaxing Incisions). Intraocular refractive interventions preserving natural human lens also include phakic lenses. Relevant categorization, examples, indications and contraindications are listed in particular chapter of this paper. Intraocular refractive surgery which replaces the original human lens is also called RLE (Refractive Lens Exchange) or PRELEX (Presbyopic Lens Exchange). These interventions are usually accompanied with the multifocal intraocular lens implantation. This chapter provides the list of specific lens types, indications and contraindications related to this type of intervention. The last chapter describes Bioptics - the combination of corneal and intraocular surgery.
